PATENT @FFICE.

or DALLAS, TEXAS Application filed March 10, 1928.' serial'No. 260,690.

This invention is an improvement upon the automatic telephone dial lighting device shown in the patent granted to me June 15th, 1926, and bearing the Number 1,588,770.

An object of .the invention is the provision of an electric light or lights mounted on a casing which encircles the dial and connected by suitable wiring to the receiver hook wiring, so that when the hook is lifted, the circuit to the lightswill be made, and same will illuminate the dial, and when the receiver is hung up the lights will be extinguished.

Another ob]ect is to provide a device of this character that may be attached readily and quickly to an automatic telephone,-and whose operation and construction is simple and durable.

Another object is the provision of a suitable switch adapted to cut off the current to the lights when it is not desired to use same.

Other objects and features will be set forth in the following description, takenin connection with the accompanying drawings, in which:

Figure 1 shows a side elevation of an automatic telephone, with the lighting device in attachment thereto.

Figure 2 shows a side elevation of an automatic telephone with the invention attached, with one section of the invention removed to better disclose the assemblage, and with part of the telephone broken away to show the manner of wiring to the lights on the casing.

Figure 3 shows a detail sectional view of the receiver hook showing the contact made when same is lifted.

Figure 4 shows a top View of the dialwith the invention attached, the right section of the invention being partly in cross section and swung away from the dial onrits pivot, to better disclose the assemblage .and means of adjustment.

Figure 5 showsa'port-ion of the dial in side view, with the invention in attachment and in cross section, taken on the line ZW in Figure '4.

Figure 6 shows a portion of the dial in side view, with the invention in attachment and in cross section, taken on the line XY, in Figure 4.

Following Figures 1 and 4, the telephone 1, of ordinary construction, rests on base 2, porcelain dial mounting 13 with metal finger dial 13 is fastened thereon by means 9 and 9*. Connection is made of wires a,-a'from contacts 6 and 7 to bulbs 14, which are mounted at intervals on the casing 10. The casing 10 is preferably madein two parts as shown in Figure 4, and is mounted in position about the dial assemblage 13 and on the base 2 by the pivot pin 11. At the head of the pin 11 and above the dial 13 is fixed the stop finger 12, the pin 11 replacing the regular affixed stop finger in attachment to the dial assemblage 13, where the same is used. The wires a-a extend about the casing 10 through the conduit 10, making contact with the elecward, and contact with member 7 therebyi ,v

making a circuit through wires aa an 7 electric current source 8. As this circuit is made, it sends a current through wires aa to light bulbs 14. 15 represents the porcelain lettered dial plate. 16 represents a pin eye by which the sections of the casing 10 may be tied into position about the dial assemblage 1.3, when the casing is constructed in sections as here shown.

It should be understood that a suitable switch may be placed at a convenient point. on the wires aa, whereby the current may be switched ofl' from the bulbs, when it is de sired to do so.

' It should also be understood that the wiring aa is insulated to prevent short circuits between its natural contact points.

-As there is no superstructure on the dial to interfere with dialing, and very little structure to get'out of order, the device is practical for this class of telephone instruments, more so than my previous invention patented for this urpose, in that the means and ease of assem lage of my present inven- "tion in no Way interferes with the general structure of the dial assemblage.

Having thus described my invention and its working, what I claim is:

1. In combination with a telephone of the automatic type having a dial plate and an apertured dial therebeneath provided with a circuit closure and means to close the circuit closure upon lifting a receiver, a casing mounted on the telephone base and extending about the dial below the dial plate, with light bulbs extending from the inner surface of the casing, and a circuit including the light bulbs and circuit closer.

2'. In combination With a telephone of the automatic type having a dial plate and an apertured dial therebeneath, a casing mounted about the dial disposed about and extending below the dial plate, and within the casing an electric wire conduit within which conduit extend electric wires for current conduction to light bulbs disposed about the inner surface of the casing and adjacent the dial, the electric wires extending from the casing to within the base of the telephone and therefrom to current supply origin.

3. In combination with a telephone of the automatic type having a dial plate and an apertured dial therebeneath, a surrounding element to the dial, and on the surrounding element lighting elements disposed for illumination of the dial, and means for the conduction of electricity from the base of the telephone through the surrounding element to the lighting elements.

In testimony whereof I hereunto aflix my signature.

FRANK L. PEYTON.
